I used a Pin No as I believe was accurate. If it was not will I be notified, I need to avoid a delay. How I can check?

To file the 2018 return you needed to enter either the 2017 AGI  or self selected PIN ... if you did not enter one of those correctly then expect the return to be rejected.  Then you can try again and resubmit the return ... expect this to cause a delay.

Can I re-submit now if I’m concerned my PIN number was not correct

[fanfare]

why do you think a second PIN would be the correct one ?
In any case, you have to wait for a REJECTED status before you can try again.

NO ... you MUST wait for the reject ... there is no other option.

While you wait take this time to check the number from 2017 so if it is rejected you have the correct one ... or use the AGI instead.
